Django app NameError however the app is installed-CodePudding

I'm trying to modify Django's built-in authetnication system by adding a custom user model. The customized model is defined inside an app named accounts:

from django.db import models
from django.contrib.auth.models import AbstractUser
from django.conf import settings

# Create your models here.

COUNTRIES = settings.COUNTRY_CHOICES

class CustomUser(AbstractUser):
    zip_code = models.PositiveSmallIntegerField(blank=True, null=True)
    city = models.CharField(blank=True, null=True, max_length=64)
    address_street = models.CharField(blank=True, null=True, max_length=64)
    address_number = models.CharField(blank=True, null=True, max_length=32)
    country = models.CharField(blank=True, null=True, choices=COUNTRIES, max_length=8)

I updated the settings.py file this way:

AUTH_USER_MODEL = accounts.CustomUser

I added accounts as an installed app:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'accounts',
    'store',
    'cart',
]

When I try to run the python manage.py makemigrations command in terminal to apply changes made to the user model Django's throwing this error:

    AUTH_USER_MODEL = accounts.CustomUser
NameError: name 'accounts' is not defined

The error is not only confined to the accounts app, no matter inside which app I try to define the CustomUser model I'm still getting it.

If anyone knows what's causing the problem please help me to resolve it.

CodePudding user response：

The AUTH_USER_MODEL setting ^[Django-doc] should be a string, not a (qualified) name, so:

# settings.py

# …

#  string literal
